To all whom it may concern: v

Be it known that I, STEPHEN A. Dommn, a citizen of the the city of St. Louis and State ofMissouri, have invented certain new and useful Improvements in Sanding-Wheels, of which the following is a specification. v

This I invention consists of an improved sanding wheel or roll that is particularly adapted for use In the accompanying .drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a side elevation of a sanding wheel with part of its covering broken away; Fig. 2 is an interior view of same; Fig. 3 is a' transverse sectional view on the line 3-3, Fig. 1; Fig. 4 is a perspec' tive view of a sanding wheel; Fig. '5 is an end elevation of the wheel depicted in Fig.

tive to the openings or sand paper 11, or the like,

v4:; and Fig. 6 is an interior view of the wheel depicted in Fig. 1.

The wheel or roll 1 is formed of wood, metal, or other suitable material and is .divided longitudinally into semicylindrical halves 2that. are attached to eachother by hinge or hinges 3. The inner surface of each half 2 is provided with agroove 4 which ex- -tends longitudinally thereof and, when said halves are folded together so that their inner surfaces meet, the grooves 4: unite to form an opening to allow a shaft 5 to extend therethrough. The periphery of wheel 1 is covered with felt 6 or other suitable material, said felt being glued or secured by other means to the periphery of said wheel and extending from the free edge of one half 2 to the free edge of the other half 2. Each half 2 is preferably provided with a metal plate 7 that is secured to the inner surface of same 8, or the like. Said plate by means of screws bears pin projections 9 and contains apertures 10, and is preferably located adjacent the free ed e of half 2. The pins 9 and apertures 10 0 .one plate 8 are so arranged rela- 10 and pins 9, respectively, of the other plate8 that, when the halves 2 are folded together so that their inner surfaces meet the pins 9 and apertures 10 of one plate enter and receive apertures 10' of the other. The emery-paper and pins 9, respectively, felt 6 is'covered with a piece of United States, residing at of plates in the manufacturing and" and other articles.

and the ends of said paper are bent over the free edgesof halves 2 in order to be attached to pins 9 8 and thereby be heldin place.

The wheel 1 depicted in Figs. 1 and 2 is relatively long and both-ends'ofsame are preferably tapered. The ends of said wheel encircle apair of externally,screw=threaded collar-s12 that is 2 by. means, ofset-screws 13, or the like.

Said collars are secured .to shaft 5 by pins 14 or otherv suitable means,

and preferably A extend beyond the ends of said wheel.

fastened to one of the halves v pair of internally screw-threadedsleeves 15 fit upon collars 12, respectively, and contain corrugations 16, or the like, cries in order to facilitate the turning of same upon said collars. Each sleeve 15 is provided with an outwardlyflaring flange 17, which is arranged to encircle a tapered end of wheel 1 in order to hold the halves 2 of said wheel firmly in engagement with each other. When the halves 2 of wheel 1 are held together by the flanges 17 of sleeves 15, the pins 9 project into apertures holdthe ends of paper 11 firmly between plates 7 whenit is desired to place a fresh piece of paper around said wheel, the sleeves 15 are turned on collars 12 so as cause flanges 17 to release the tapered ends of Wheel 1 and thereby allow the halves 2 to be spread apart, whereby the ends of the old piece of emery-paper can be detached from pin 9 and a new piece of emery-paper can be substituted in lieu of the old piece. In order to hold the halves 2 of wheel 1 firmly together while the shaft 5 rot-ates said wheel, one of said collars is provided with righthanded thread and the other of said collars with a left-handedthread, and said shaft is rotated in the direction to cause sleeves 15 to have a .tendency to tighten their grlps upon the tapered ends of said wheel.

The wheel 1 depicted in Figs. 4 and 5 is one end of same is tapered said wheel is rovided with a depression 18 into which a ange 19- on collar 12 projects, said flange being fastened to one of the halves 2 by screws 20 or other suitable means.

Said collar 12 is secured to shaft 5 by a pin 14 or the like, and extends beyond the tapred end of said wheel in order to receive a sleeve.15. The flange 17. of said sleeve is adapted to encircle the tapered end of said.

in their periphp 10 and .relatively narrow and for this reason'only Each half 2 of v wheel and, also, to hold halves 2 of same firmly together. The periphery of felt 6 is covered 'with a strip of emery-paper, and the ends of said paper are attached to pins 9 inand it should be understood that same can be made convex or concave or conlcal, if so desired. The emery-paper 11 that covers a wheel 1 can be readily replaced by fresh emery-paper, as hereinabove described without the necessity of removing said 'wheel from shaft 5.

I claim: I

1. In combination with a shaft, a collar rigidly mounted on said shaft and having its outer end exteriorly threaded, a hollow member formed with a recess conformably receiving the collar, means to secure said member rigidly to said collar, a second hollow member hinged to the first namedmember andhaving a recess conformably receiving said collar, said members conjomtly extending over and completely inclosing the unthreaded portion of the collar, each of said members having one end thereof tapered, and a sleeve threaded internally to engage the threaded part of said collar and formed with an inner flaring flange to enwitnesses.

gage said tapered ends of the hollow memers.

ameter than said collar, the adjacent end of 2. In combination with a shaft, a collar said member being formed with a depression to conformably receive said flange, a second hollow member hinged to the first named member, and having a recess to conformably receive said collar and a depression in one end to conformably receive said'flange ,'said members conjointly extendin over'and completely inclosing the unthrea, ed part of said collar and the entire width of the flange, each of said members having their opposite ends tapered, and a sleeve threaded on said threaded part of the collar and having a flared end to engage the tapered ends of said members. 7 y

In testimony whereof I have hereunto aflixed my signature in the presence of two STEPHEN A. DOBYNEQ Witnesses:
